Electric sliding insulated doors made by Leehwa
Polytech are perfect safety devices comprised of special
gears and controllers to ensure the highest levels of convenience.
As the doors have handles which allow the doors to be
opened in emergencies, people can safely escape in the case
of a blackout or other danger.

100% compliance with HACCP
No woods or cast-iron products are used and HACCP standards are met by using finishing goods made from aluminum and stainless steel.

High safety
When foreign substances occur or the doors are over-loaded, control panels automatically control the doors.

Light and smooth door
The weight of a door has been reduced to about 1/3 of standard doors, so it can be softly opened and closed.

Automatic open and closure
When foreign substances occur, the doors automatically open and close like elevators.

New BLDC motor applied
Semi-permanent life, innovatively engineered low noise and strong power

Simplified chain
Disadvantages of existing door chains have been perfectly overcome. A/S 0%

New antibiotic silicon packing employed
Using soft rubber with a good restitution force, a high degree of insulation is guaranteed.

In a way of 8-channel mode remote control
One remote control device can operate up to eight doors.
